ROOFS: TYPES AND STRUCTURE INCLUDING THE PLAN/DETERMINATION OF PITCH ANGLE
How to draw a roof outline
1.) Import or draw floor plan: Start by drawing a new floor plan or importing an existing one.
2.) Adjust wall and room dimensions: With your floor plan drawn, you can now start tweaking the design to make sure it will fit well with the roof you have envisioned for the final product.
3.) Select roof type: Your floor plan should now be exactly how you want it to be. Now, choose the type of roof you want that suits the house design.
Types of roofs
I.) Gable Roof: This is one of the most common roof types, with two sloping sides meeting at a ridge. It forms a triangle shape at the end, called a gable.
II.) Hip Roof: A hip roof has slopes on all four sides, with each side meeting at the top to form a ridge. It's more stable than a gable roof and provides better resistance to strong winds.
III.) Flat Roof: As the name suggests, this type of roof is nearly level with a slight pitch for drainage. It's commonly used in modern architecture and for commercial buildings.
IV.) Gambrel Roof: Often seen in barns and Dutch colonial houses, a gambrel roof has two distinct slopes on each side. The lower slope is steeper, while the upper slope is shallower.
V.) Mansard Roof: This style has a double slope on all four sides, with the lower slope being much steeper than the upper. It creates additional living space in the attic and is popular in French architecture.
VI.) Shed Roof: Also known as a lean-to roof, it has only one slope and is typically attached to a taller wall. It's commonly used for additions, porches, and sheds.
4.) Draw roof automatically or manually: These can be done using either AutoCAD or by doing it yourself with your drawing tools.
5.) Adjust roof parameters: After you’ve automatically generated your roof or drawn it manually, you’ll need to make a few small adjustments to make sure you have it exactly right.
6.) Define edge parameters: Here, you define the ridge start, overhang, underside, and ridge valley of your roof.
7.) Add exterior features: You can now add dormers, gutters, and downspouts.
EVALUATION: 1. Design a roof plan for a one room apartment.
